High-Power Brushless Motor Speed Controller 3-phase Regulator PWM Brushless Motor Speed Controller Drive DC 12V 30A Feature: With micro single-chip system, this speed control can achieve simple system programming, which can suit better high-speed high-power brushless motors. It has several functions: 1.Safety Startup: To avoid any injury, the motor will not start up immediately if the potentiometer of speed controller is not at the lowest gear, which is necessary for high-speed high-power motor to protect user\'s safety. 2.Temperature Protection: The speed control has aluminum heat sink, which allows it work at 30 A continuously. When temperature reaches 110 celsius degree, temperature detect system will send a protection signal and system will auto decrease 60% power output to protect speed control and motor. It will back to normal power after temperature is decreased. To protect the actuator module, please dissipate heat during long-time using. 3. The signal loss prevention: Auto shut down when there is no signal detected from PWM signal generator(potentiometer ). 4. Power Identification System: The speed control has power identification system, which is designed for high-speed high-power motors such as in model plane. It is not suitable for low-power brushless motors. 5, Programming Functions: With single-chip control system, some functions could be altered: a, Startup: Flexible slow startup/direct startup b, Braking: Reverse load quick braking/free braking c, Adjustable Timing: Small/medium/large d, Low Voltage Protection: Low/medium/high e, Battery Types: Lithium /nickel chrome/NIMH/plumbic acid 6. Back to Factory Settings: Wrong operation can be cleared 7. Other Function(please ignore if only used for motor drive ) : The external PWM signal generator can send signal to control speed or to turn steering gear, therefore it can test steering gears less than 55 g. Specification: Rated voltage: DC 6-12.8V Current rating: 32A (within 5s, max current can not exceed 40A) Nominal power: 360W Rated Power: 5V 0.5A Temperature protection: 110°C Speed range: 8%~98% For motor poles: 2-18 pole Start: flexible start/immediate start Brake: reverse load /no brake Speed signal: 8KHz/16KHz fixed frequency PWM _x000D_ _x000D_
